Embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figure 1, the utility model provides a kind of multifunction electronic display image processor, it comprises signal input module, signal output module, All-in-One controller, character controller and single chip part, signal input module comprises multiple SDI decoding unit and multiple memory cell, each SDI decoding unit comprises the CLC014 chip of connecting successively, CLC016 chip and CLC011 chip, each memory cell comprises video image storage chip and video image storage control chip, video image storage chip adopts μ PD42280 chip, video image storage control chip adopts fpga chip EPM7064, All-in-One controller comprises All-in-One control unit, single image control unit and selected cell, All-in-One controller adopts fpga chip EPM9320.

In the present embodiment, be three-in-one video image processor, stimulus part is " SDI decoding and the storage " unit in Fig. 1.Such unit one has 3 pieces, processes video signal SDI_1, SDI_2 and SDI_3 that 3 tunnels are different respectively.This 3 road signal enters this three-in-one video image processor by SDI interface, and its form all meets SDI interface standard, and transmission rate is 300Mbps.

The basic structure of whole SDI decoding and memory module is shown in Fig. 2, and CLC014, CLC016, CLC011 chip in Fig. 2 is all ready-made chip.First enter CLC014 and CLC016 chip by the vision signal of SDI interface, adaptive cable equalization is carried out to this serial digital video signal and data are retimed phase-locked.Then realized the decoding of serial digital video by CLC011 chip, change into by original serial digital video signal meet ITU-R BT656 international standard, transmission rate is 27Mbps, and 10 parallel-by-bits export.

The storage of the then settling signal of two modules below in Fig. 2.Wherein, " FIF0 storage " is exactly the push-up storage for cache image, according to the capacity of the video image that will store, the μ PD42280 chip of NEC Corporation is directly adopted in the present embodiment, this chip capacity is 256KX8 bit,, it is controlled by 3 control signals respectively to the read-write of data.And can use owing to there is no ready-made chip the control that image stores, therefore, controller when using one piece of fpga chip EPM7064 of altera corp to store as image in the present embodiment.

Finally can complete single image display all over the screen due to image processor of the present utility model or All-in-One split screen shows two kinds of functions, therefore the storage of image also has two kinds of different situations.During four-in-one situation, the Pnin1 signal that single-chip microcomputer provides is effective, and because multiple image is simultaneously displayed on a display screen, every piece image only accounts for the 1/n of display screen, when single image display all over the screen, and Pnin1 invalidating signal, the image display all over the screen of required display.
